Natural Language Processing Techniques

NLP is a multidisciplinary field that draws on linguistics, computer science, mathematics, and psychology.

Some of the standard NLP techniques are:

  • Sentiment Analysis: The process of identifying and extracting emotional tone and attitude of text or speech, like positive, negative, or neutral.
  • Named Entity Recognition: The process of locating and classifying named entities in text or speech, like person names, organization names, locations, dates, etc.
  • Text Summarization: Creating concise and coherent summary of longer text or speech, preserving main points and information.
  • Topic Modeling: The process of discovering and extracting latent topics or themes from collection of texts or addresses, like news articles, books, reviews, etc.
  • Text classification: The process of assigning text or speech to one or more predefined categories or labels, like spam or ham, positive or negative, sports or politics, etc.
  • Keyword Extraction: Identifying and extracting most relevant and salient words or phrases from text or speech, like keywords, keyphrases, hashtags, etc.
  • Lemmatization and Stemming: The process of reducing inflected forms of words to their base or root form, like running to run, cats to cat, etc. Lemmatization considers context and meaning of the phrase, while stemming applies set of rules based on the word’s suffix.
  • Part of speech Tagging: The process of allotting part of speech tags each word in text or speech, like nouns, verbs, adjectives, adverbs, etc.
  • Named Entity Linking: The linking of named entities in a text or speech to their corresponding entries in knowledge base or database, like Wikipedia, IMDb, etc.
  • Question Answering: Natural Language queries posed by users like who, what, when, where, why, and how efficiently and directly is our aim.
  • Machine Translation: Translation refers to the practice of translating text or speech from one natural language into another natural language for instance English into French or Chinese into English, for instance.

Natural Language Processing Examples

NLP has many applications in some domains and industries. Some of the examples are:

  • Email Filtering: NLP can assist in filtering out unwanted or malicious emails by using text classification techniques to recognize spam emails based on their content and sender details.
  • Intelligent Assistants: NLP can enable intelligent assistants such as Siri, Alexa, Google Assistant, and others to understand and respond to natural language queries from users by using speech recognition techniques, natural language understanding techniques, natural language generation strategies, and dialogue management methodologies.
  • Search Engines: NLP can improve quality and relevance of search results by using keyword extraction, query expansion, document ranking, document summarization, and question answering techniques to match user’s queries with most appropriate web pages or documents.
  • Social Media Platforms: NLP can help analyze and monitor the social media activity and sentiment of users by using sentiment analysis, named entity recognition, topic modeling, text classification, and keyword extraction techniques to extract insights and trends from social media posts and comments.
  • Financial Trading: It can help predict market movements and trends by using sentiment analysis, named entity recognition, topic modeling, and text classification techniques to analyze news articles, financial reports, tweets and other sources of financial information.
  • Medical Diagnosis: NLP can help diagnose diseases and conditions by using named entity recognition, called entity linking, text classification, and question answering techniques to analyze the medical records, symptoms, test results, and medical literature of patients.
  • Customer service: It can help provide better customer service by using text summarization, text classification, sentiment analysis, and question answering techniques to handle customer queries, complaints, feedback, and reviews via email, chatbot, or phone call.
  • Content Creation: NLP can help create original and engaging content using natural language generation, text summarization, keyword extraction, and machine translation techniques to generate headlines, captions, articles, blogs, stories, poems, songs, etc.
  • Fraud Detection: It can help detect and prevent fraud by using text classification, named entity recognition, called Entity linking, and sentiment analysis techniques to identify fraudulent transactions, claims, invoices, emails, etc., based on their content and context.
  • Law Enforcement: It can help solve crimes and enforce laws by using named entity recognition, named Entity linking, text classification, text summarization, and question answering techniques to analyze crime reports, evidence, witness statements, court documents, and legal databases.
